Fig. 1 is a kind of flow diagram of voice communication data detection method provided by the embodiments of the present application, and this method can To be executed by voice communication data detection device, wherein the device be can be implemented by software and/or hardware, and can generally be integrated in movement In terminal.As shown in Figure 1, this method comprises:

After voice communication group in step 101, default application program is successfully established, detect that detecting event of uttering long and high-pitched sounds is touched Hair.

Illustratively, the mobile terminal in the embodiment of the present application may include the mobile devices such as mobile phone and tablet computer.It is default Application program can be the application program of built-in voice group call function, such as online game application, Online class application, video Conference applications or the other applications for needing multiple person cooperational etc..

Illustratively, 2 members be may include in voice communication group, but in most cases, generally comprise 3 or 3 with On member, the voice communication between 3 or 3 or more mobile terminals can be realized.Voice communication group can be by movement It is initiated and is established using the user of default application program in terminal, after voice communication group is successfully established, wrapped in voice communication group It can be communicated between all mobile terminals contained.In general, being also not in earphone mould when mobile terminal is not in silent mode When formula, it will be appreciated that be in outer mode playback for mobile terminal, the sound of each user can be used by oneself in voice communication group Mobile terminal microphone acquisition, and after network transmission and processing by the loudspeaker of the mobile terminals of other users into Row plays.By taking game application as an example, such as the association's war that needs to form a team, phonetic function of forming a team can be opened, it is assumed that there are 5 players in team, that After voice communication group is successfully established, this 5 people can converse between each other, any one player can hear separately simultaneously Outer 4 player's words, seemingly other 4 players oneself are talking equally at one's side, facilitate the game in exchange.Present techniques The executing subject of scheme, i.e., current mobile terminal can be any one mobile terminal in voice communication group, be also possible to Some or certain several specified mobile terminals in voice communication group.That is, can be by any one in voice communication group Mobile terminal execution method provided by the embodiments of the present application, can also be by specified one or more mobile terminal execution the application Embodiment provide method, can also all mobile terminals be performed both by method provided by the embodiments of the present application.

In general, not only including in the collected sound of mobile terminal microphone when mobile terminal is in outer mode playback User itself one's voice in speech, it is also possible to include the sound that the default application program itself that loudspeaker plays issues, such as background sound It is happy etc., it is also possible to the sound comprising ambient enviroment, it is also possible to which that other people speak in the voice communication group played comprising loudspeaker Sound, in this way, when the data comprising various sound respectively acquired are sent to the same shifting by network by multiple mobile terminals It (such as include 5 mobile terminals in voice communication group, then wherein 4 mobile terminals will be respectively acquiring when dynamic terminal Sound is sent to server, and server gives the audio data transmitting of 4 mobile terminals to the 5th mobile terminal), these sound by Broadcasting can be mixed in the mobile terminal, may generate phenomenon of uttering long and high-pitched sounds.

In the embodiment of the present application, in order to carry out detection of uttering long and high-pitched sounds on suitable opportunity, detecting event of uttering long and high-pitched sounds can be preset The condition being triggered.It optionally, can be in the voice in default application program for the real-time detection timely and effectively uttered long and high-pitched sounds After phone group is successfully established, detecting event of uttering long and high-pitched sounds is triggered immediately；Optionally, detection of uttering long and high-pitched sounds is carried out in order to more targeted, together When save detection of uttering long and high-pitched sounds operate brought by extra power consumption, theory analysis or investigation can be carried out to the scene uttered long and high-pitched sounds is easy to happen Deng reasonably default scene being arranged, when detecting that mobile terminal is in default scene, triggering is uttered long and high-pitched sounds detecting event.

Step 102, the downlink voice communicating data for obtaining predetermined time period in mobile terminal, and to the downlink language Sound communicating data carries out piecemeal processing, obtains M data block.

Illustratively, downlink voice communicating data can be the corresponding server of default application program to receive voice logical In words group after the voice data of other mobile terminals, the data of mobile terminal are given by audio mixing etc. haircut, or directly turn Issue the data of mobile terminal, the application to the processing modes of server process voice communication data without limitation.It is existing in correlation Have in technology, after mobile terminal receives downlink voice communicating data from server, played out by loudspeaker, without into Capable detection of uttering long and high-pitched sounds.In the application, after detecting that detecting event of uttering long and high-pitched sounds is triggered, downlink voice call number will not be directly played According to, but downlink voice communicating data is analyzed, to judge in downstream voice data with the presence or absence of sound of uttering long and high-pitched sounds.

In the embodiment of the present application, predetermined time period can according to the concrete configuration of mobile terminal, data-handling capacity and The demand of voice communication to timeliness etc. is because usually determining, the embodiment of the present application is without limitation.For example, can be between 1 to 2 second Any duration.Carrying out piecemeal processing to downlink voice communicating data can be according to the progress piecemeal processing of default unit length, Default unit length for example can be 40 milliseconds.Assuming that predetermined time period is 1.2 seconds, presetting unit length is 40 milliseconds, that 30 data blocks, i.e. M=30 can be divided into.

Step 103 is successively analyzed in current data block using presupposition analysis mode and is uttered long and high-pitched sounds a little with the presence or absence of doubtful, will for the first time There is the doubtful data block uttered long and high-pitched sounds a little and is determined as initial data block.

The application is not especially limited presupposition analysis mode.For example, the presupposition analysis mode includes: to obtain on frequency domain Energy value in high-frequency region is taken to calculate preset quantity around the frequency point to be determined higher than the frequency point to be determined of preset energy threshold value The capacity volume variance value of frequency point determine that the frequency point to be determined is doubtful when the capacity volume variance value is greater than default discrepancy threshold It seemingly utters long and high-pitched sounds a little；The high-frequency region is the frequency range that frequency is higher than predeterminated frequency threshold value.

Illustratively, for current data block, frequency domain can be first transformed from the time domain to, spectrum analysis is convenient for.Become The mode the embodiment of the present application of changing without limitation, can use Fourier transformation mode, such as the fast algorithm of discrete fourier transform (Fast Fourier Transformation, FFT).By taking 40ms as an example, the audio data (16bit, 16k sample rate) of 40ms Size is 40*16*16/2=1280 byte, is adapted for use with 1024 and does FFT transform progress spectrum analysis, after FFT is handled Frequency analysis in frequency range be 0~16K/2, step-length be (16K/2)/1024, step-length is about 8Hz.

In the embodiment of the present application, high-frequency region and other regions can be divided using predeterminated frequency threshold value as cut off value.In advance If frequency threshold can be configured according to the actual situation, such as can according to voice frequency and be easy to appear the frequency feature of howling into Row setting, such as can be 1KHz, 1.5KHz or 2KHz etc..Such as predeterminated frequency threshold value is 2KHz, that is, is greater than the portion of 2KHz It is divided into high-frequency region.The frequency of general howling appears in high-frequency region, and sound is larger (i.e. energy value is higher), the application Embodiment can quickly determine doubtful uttering long and high-pitched sounds a little in a data block according to energy value characteristic distributions.

Illustratively, the corresponding energy value of each Frequency point (abbreviation frequency point) in data block is obtained, then from high-frequency region In find energy value be higher than preset energy threshold value frequency point to be determined, calculate the energy of the frequency point of preset quantity around frequency point to be determined Measure difference value.Preset energy threshold value and preset quantity can be arranged according to actual needs, for example, preset energy threshold value can be- 10dB, preset quantity can be 8 (before frequency point to be determined 4 and 4 below).By taking step-length above is about 8Hz as an example, it is assumed that The frequency values of frequency point to be determined be 3362Hz, then around it frequency values of frequency point of preset quantity be about 3330Hz, 3338Hz, 3346Hz, 3354Hz, 3370Hz, 3378Hz, 3386Hz and 3394Hz.Capacity volume variance value is for measuring frequency point to be determined and surrounding Difference degree between the frequency point of preset quantity specifically can be the difference of maximum energy value and minimum energy value, can also be energy Variance yields or energy mean square deviation etc. are measured, the application is without limitation.Preset discrepancy threshold and corresponding, the example of capacity volume variance value Such as, when capacity volume variance value is energy variance yields, presetting discrepancy threshold is default variance threshold values.When capacity volume variance value is poor greater than default When different threshold value, illustrate frequency point to be determined than more prominent, is very likely to be to utter long and high-pitched sounds a little, accordingly, it is determined that frequency point to be determined is doubtful It utters long and high-pitched sounds a little.In this way setting can rapidly and accurately identify it is doubtful utter long and high-pitched sounds a little, lay the foundation to improve detection efficiency of uttering long and high-pitched sounds.

Illustratively, there may be multiple frequency points to be determined in a data block, the application can be highest from corresponding energy Frequency point to be determined starts to carry out the doubtful judgement uttered long and high-pitched sounds a little.

Illustratively, it is analyzed in first data block using above-mentioned presupposition analysis mode and is uttered long and high-pitched sounds a little with the presence or absence of doubtful, if In the presence of then doubtful utter long and high-pitched sounds a little first appears, and first data block is determined as initial data block；If it does not exist, then by current number According to next data block of block as new current data block, and new current data block is analyzed using above-mentioned presupposition analysis mode In utter long and high-pitched sounds a little with the presence or absence of doubtful.And so on, it is determined as initial data block until first appearing the doubtful data block uttered long and high-pitched sounds a little, If uttering long and high-pitched sounds a little there is no doubtful in M data block, it is believed that not including sound of uttering long and high-pitched sounds in current downlink voice communicating data.

Step 104, from initial data BOB(beginning of block), successively with n data block be data segment to be analyzed, using presupposition analysis Mode analyzes include in current data section doubtful and utters long and high-pitched sounds a little, when the doubtful frequency uttered long and high-pitched sounds between a little for including in N number of data segment When rate difference is in preset range, determine there is sound of uttering long and high-pitched sounds in downlink voice communicating data.

Wherein, n=2,3 ..., N；N is less than or equal to M, is greater than or equal to 2；The starting point of each data segment with it is described The starting point of initial data block is identical, and the initial data block is first data segment.By taking above-mentioned M=30 as an example, 2≤N≤ 30.When carrying out spectrum analysis, data length to be analyzed can have an impact analysis result, because when data point is less, essence Degree may not be too accurate, so, it is analyzed again using the larger data of length, has been equivalent to a modified place Reason, can more accurately determine whether to utter long and high-pitched sounds.The application to the specific value of N without limitation, it is assumed that N=4, a data The length of block is 40ms, then the time range of initial data block can be denoted as 0 to 40ms, since initial data block has been analyzed Finish, and as the first data segment, so being second data segment since n=2, the time range of second data segment can be remembered It is 0 to 80ms, and so on, the time range of third data segment can be denoted as 0 to 120ms, the time model of third data segment 0 can be denoted as to 160ms by enclosing.

Illustratively, preset range can be arranged according to the actual situation, such as can be 40Hz (such as the example above can recognize To be equivalent to 5 step-lengths).Assuming that the doubtful frequency uttered long and high-pitched sounds a little that 4 data piecewise analysis come out is respectively A, B, C and D, and A, B, There is sound of uttering long and high-pitched sounds in downlink voice communicating data within 40Hz, then can determine in C and D mutual difference.

Optionally, if doubtful utter long and high-pitched sounds for including in current data section a little doubtful is uttered long and high-pitched sounds a little with include in the data segment of front Between frequency difference be not in the preset range, then from next data BOB(beginning of block) of current data section obtain it is described pre- If the downlink voice communicating data of time span, and repeat the related behaviour that piecemeal processing is carried out to downlink voice communicating data Make.The advantages of this arrangement are as follows can be said when the doubtful frequency distance uttered long and high-pitched sounds a little for including in any two data segment is larger Doubtful utter long and high-pitched sounds of bright front a little may not be really to utter long and high-pitched sounds a little, need to continue to test, without to subsequent data segment into The doubtful detection of uttering long and high-pitched sounds of row, saves power consumption, improves utter long and high-pitched sounds sound detection efficiency and accuracy.For example, working as C and A or the difference between B It is different exceed 40Hz when, then since 120ms, reacquire mobile terminal in predetermined time period downlink voice converse number According to, and piecemeal processing is carried out to the downlink voice communicating data, M data block is obtained, then determine new initial data block, and Continue to determine using aforesaid way in downlink voice communicating data with the presence or absence of sound of uttering long and high-pitched sounds.

The voice communication data detection method provided in the embodiment of the present application, the voice communication preset in application program are set up It after standing successfully, detects that detecting event of uttering long and high-pitched sounds is triggered, obtains the downlink voice call of the predetermined time period in mobile terminal Data, and carry out piecemeal processing；It is successively analyzed in current data block using presupposition analysis mode and is uttered long and high-pitched sounds a little with the presence or absence of doubtful, it will It first appears the doubtful data block uttered long and high-pitched sounds a little and is determined as initial data block；From initial data BOB(beginning of block), successively it is with n data block Data segment to be analyzed is analyzed include in current data section doubtful using presupposition analysis mode and uttered long and high-pitched sounds a little, when N number of data segment In include the doubtful frequency difference uttered long and high-pitched sounds between a little when being in preset range, determine to exist in downlink voice communicating data and make a whistling sound It is sound.By using above-mentioned technical proposal, can the voice communication group of default application program in the terminal be successfully established Afterwards, detection of uttering long and high-pitched sounds accurately is carried out to downlink voice communicating data, taken appropriate measures so as to subsequent, reduction utters long and high-pitched sounds sound to use Family is inconvenient using bring.
